摘要
以桃树大久保为试材,研究果树干注营养液对其生理指标及叶片元素的影响。结果表明,果树干注营养液不同程度地增加桃树新梢生长量、叶面积、萌芽率、坐果率及叶片光合速率。同时施用干注营养液显著增加桃树叶片中大量元素N,P,K,Ca及微量元素Fe,Mn,Cu,Zn,B的含量。干注营养液对促进桃树生长发育、提高树体的营养水平具有显著效果。
＇ Okubo＇ peach trees were selected to study the effect of stem-injected nutrient solution on some physiological indices and leaf mineral element contents. Our results demonstrate that shoot growth, leaf area, germination rate, fruition rate and photosynthetic rate in leaves were increased in various degrees after stem injected nutrient solution. Besides, the contents of maeroelement N, P, K, Ca and the contents of microelement Fe, Mn, Cu, Zn, B were significant increased in peach tree leaf by using of stem-injected nutrient solution. The results showed that stem-injected nutrient solution has remarkable effect on promoting the peach tree growth and improving its nutrition level.
